Microsoft is still busy readying its upcoming technology preview of Windows 9, but details continue to emerge about the company's plans for the future of Windows. WinBeta reports that Windows 9 will include interactive Live Tiles and a notification center. Microsoft has previously experimented with interactive Live Tiles as part of a research effort earlier this year, and The Verge understands it's planning to include this work in Windows 9, currently codenamed Threshold. The Live Tile work, which is surfaced on the new mini Start Menu, coincides with additional changes to the desktop UI that Microsoft is currently testing. A notification center will also be present, similar to the implementation in Windows Phone 8.1 recently.

Both of these features are expected to ship in the final version of Windows Threshold, expected to be named Windows 9, but they will not be included in the Technology Preview that's due to be distributed late next month. Sources familiar with Microsoft's plans tell The Verge that the company will be updating the Technology Preview once or twice a month to add new features for testers, and the notification center and interactive Live Tiles will come later in testing
